hua gain » heat gain, run gain, hua ban
yang jin » yang jie, ying jin, shang jin
yang jun » yang jui, pang jun, yang judy

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wing kang) OR (jin kang)) han hua gain ((yang jin) OR (yang jun)) long han ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing kang) OR (jin kang)) han hua gain ((yang jin) or (yang jun)) long han ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing kang) OR (jin kang)) han hua gain ((yang jin) or (yang jun)) long han ;*.
